Hi Tim, could you please provide me with the diagram how you wired references between 24VDC of power supply and 10VDC of drive? I do not fully understand that point and I see difference between reading of my analog Voltage meter (Powered by 24VDC) and Powerfex drive.
Hi Luke, see if page 42 helps. Terminal 14 must be connected to the 0V of your 24VDC power supply so that they have the same reference point. literature.rockwellautomation.com/idc/groups/literature/documents/um/520-um001_-en-e.pdf
For the most part the device will specify it. The Powerflex can use a 1K to 10K ohm 2 watt potentiometer. I use a 5K because it works with many of our other analog exercises. Common ones would be 5K and 10K.
Hi Tim, I had experience with 2 30hp VFD's with a Analog out of one to the input of the other. It worked fine, until the 600' drag link chain began to wear in the nylon track. It was a nightmare !
Is that powerflex 525 single or three phase in, if three phase how are you operating it? I'm only asking because everything I found on it shows three phase. Thanks

Hi Tim, got it now! Thanks a lot for explenations!
Random question, how do you determine what size potentiometer you need per your system setup

I bet! When you need two motors to stay in sync, it is hard to beat an encoder feedback setup. We've got a video on that coming soon.
@@TimWilborne Great ! Good Stuff.
Its the Black Magic behind the curtain!
What type of analog readout are you using?
Can you control a vfd with a 4-20ma signal without a plc?
Sure, it is done all the time, where is your 4-20mA signal coming from?
@@TimWilborne can the drive create its own signal?

It is a 120VAC input Powerflex 525 drive. All of our trainers are designed to plug directly into a standard wall outlet.
FO13 Why do I get ground fault when starting motor
That means you have leakage current between the motor windings and ground. Either the motor has got wet or the windings are failing.

How to wire a Allen Bradley 525 Drive to run off 4 to 20 V input speed
Have a look at P47, you just need to change that parameter.
Which terminals? 14 and ???
16 is the analog output.
please upload video about inverter
Is there something specific you are looking for? We have lots of videos about inverters.
What is the accuracy of analog output if it is used for measurung current
I actually talk about that in an upcoming video, hear is a sneak peak.
